本节内容 为什么要用版本控制？ 假设你在的公司要上线一个新功能，你们开发团队为实现这个新功能，写了大约5000行代码，上线没2天，就发现这个功能用户并不喜欢，你老板让你去掉这个功能，你怎么办？你说简单
简介扩展并增强 datetime 模块的功能。支持 Python 2.3+。官方文档 :http://labix.org/python-dateutil安装两种方法:easy_install :easy_install python-dateutilpip在线安装 :pip install python-dateutil方法1，parse字符串可以很随意，可以用时间日期的英
demo#!/usr/bin/pythonclass Person:name = jimage = 25def say(self):print My name is + self.name + , and age is + str(self.age)p = Person()p.say()print p.name
一、安装MySQL-python# yum install -y MySQL-python二、打开数据库连接#!/usr/bin/pythonimport MySQLdbconn = MySQLdb.connect(user=root,passwd=admin,host=127.0.0.1)conn.select_db(test)cur = conn.cursor()三、操作数据库def insertdb():sql = insert
一、语法#!/usr/bin/pythonfilename=hello#try except finally demotry:open(abc.txt)print helloexcept IOError,msg:print the file not existexcept NameError,msg:print hello not definedfinally:print end#throw exceptionif filename == hello:raise Ty

读取JSON文件可以用JSON库，示例代码：#coding:utf-8import jsonwith open(msg.json) as jsonfile:json_data = json.load(jsonfile)for key in json_data:val = json_data[key]print key + t + val
一、Python Base64编码Python中进行Base64编码和解码要用base64模块，代码示例：#-*- coding: utf-8 -*-import base64str = cnblogsstr64 = base64.b64encode(str)print str64 #Y25ibG9ncw==print base64.b64decode(str64) #cnblogs二、MD5#Python 2.ximport
